HEATER, FOR DRINKING-FOUNTAINS.

Application filed December 21, 1912.

To all whom it may concern Be it known that we, HARRY L. Fisrrnn and EDWIN M. S. Fisnnn, citizens of the United States, residing at Muscatine, in the county of Muscatine and State of Iowa, have invented certain new and useful Improvements in Heaters for Drinking-Fountains, of which the following is a speciflca' tion, reference being had therein to the ac conipanying drawing.

This invention relates to a heater for drinking fountains which are especially adapted to be used by fowls,vand has for its object the production of an eflicient means whereby the same may be heated for pre venting the water contained therein, from freezing during the cold weather.

Another object of this invention is the production of a lamp housing carried by the tank, said lamp housing being provided with a flue means for allowing the products of combustion to pass from the lamp chamber.

Another object of this invention is the production of a heat reflecting plate carried by the lamp which is adapted to reflect the heat upon the body of the tank.

lVith these and other objects in view this invention consists in general of certain novel combinations, constructions, and arrangement of parts, as will be hereinafter fully described, illustrated in the accompanying drawing, and specifically claimed.

In the accompanying drawing: Figure 1 is a rear elevation of the device showing the door in an open position. Fig. 2 is a longitudinal section of the lamp housing showing a portion of the tank in transverse section. Fig. 3 is a detailed perspective view of the lamp and the heat reflecting plate used in combination therewith. Fig. 4 is a perspective view of the flue member and hood showing a portion of the lamp housing and tank.

Referring to the accompanying drawing by numerals it will be seen that the device consists of the tank 1 which is cylindrical in shape and which carries at its forward end the rim 2 which is adapted to rest upon the ground. Mounted upon the top of the tank 1 there is a handle 3 which is adapted to carry the device from place to place when it is so desired. The rear end of the tank 1 is provided with a rim 4, and the back 5.

Positioned upon the lower side of the tank Specification of Letters Patent.

1 and at the rear end thereof, there is a lamp housing which comprises the side walls 6 and 7 which are fixedly connected to the bottom 8. The upper portions of these side walls 6 and 7 are attached to the body of the tank 1. In order to close the forward end of the casing there is provided a backing 9. The side wall 7 carries a pivotally mounted door 10 which is concave on its upper edge, and which carries upon its edge the laterally extending flange 11 which is adapted to it over the rim 4 when the door is in a closed position whereby to prevent the weather from entering into the lamp chamber or housing. One end of this door 10 is provided with the bent portion 12 upon which is mounted the spring 13 which is adapted to engage the lug 14 carried by the side wall 6, whereby the door will be held in a closed position.

Each side wall 6 and 7 is provided with a bulged portion which constitutes a flue. This flue comprises the sides 15 which are integrally connected to the back 16. The lower portion of this back being bent in as illustrated at 17, while the sides being tapering as shown at 18 for allowing the por tion 17 to be bent inwardly, whereby there is provided an opening 19 which is adapted to allow the air to enter the lamp housing. It will also be seen that the bottom 8 is provided with a laterally extending bent portion 20 which extends above this opening 19 whereby the air will be prevented from blowing there-through and striking the lamp member whereby the flame would be extinguished.

By referring to Fig. 2 it will be seen that the air will have to pass upwardly as indicated by the arrow, before the same can enter the housing. The upper portion of the flue extends evenly throughout its entire length so as to providethe enlarged opening 21 which is adapted to allow the products of combustion to pass freely from the interior of the housing. Carried by the body of the tank 1, and positioned over the enlarged opening 21, there is a hood 22 which is provided with an inclined top 23. It will be seen that by use of this hood the weather will be prevented from passing into the lamp housing by means of the large opening 21, and the wind will also be diverted so as to prevent the same from passing down through this enlarged opening 21 and extinguishing the flame. By use of this flue it will be seen that the air enters through the opening 19 and will pass freely into the lamp housing, while the products of combustion will pass out through the enlarged opening 21 and down under the lower portion of the hood as indicated by the arrow. Positioned within this lamp housing there is a lamp which comprises a rectangular body 24 which carries the handle 25 which facilitates the insertion or removal of the lamp relative to the lamp housing. The upper portion of the body 24 carries the burners 26. Vv hen the lamp is placed within the lamp housing these burners are so arranged as to allow the flames to extend up the side portions of the tank 1 whereby a considerable area of the same will be heated. There is also provided a heat reflecting plate which comprises the bowed body 27 which carries at each end the laterally extending portions 28 in which the transverse extending slots 29 are formed. l/Vhen the lamp is in its correct position, the burners 26 pass through the slots 29 as illustrated in Fig. l, for supporting the plate. It will be seen that by use of this plate the bowed portion 27 conforms to the contour of the cylindrical body 1 and will form a heat reflecting means for reflecting the heat upon the body 1 as the same circulates within the lamp housing.

From the foregoing description it will be seen that an eflicient heater for a watering device for fowls has been produced which is provided with flue members which are adapted to support combustion and to allow the products of combustion to pass through the lamp housing and also with a simple means for reflecting heat upon the body as the same circulates Within the housing.

Having thus described the invention what is claimed as new, is

In a device of the class described, the combination with a body, a lamp housing carried by the rear end of said body, a flue means positioned upon each end of said housing, a lamp positioned within said housing and provided with a plurality of burners, a heat reflecting plate provided with a bowed portion which is adapted to conform to the contour of said body, the outer portion of said bowed portion being provided with laterally extending portions provided with transversely extending slots, said burners passing up through said slots for supporting said plate at a distance from said body for reflecting heat upon said body as it circulates within said housing.

In testimony whereof we hereunto aflix our signatures in presence of two witnesses.
